            This page offers a simple DHCP leases search engine. It utilizes Kea control channel to find leases by an IP
            address, delegated prefix, client identifier, DHCPv6 DUID, or hostname. Type one of these parameters in the
            search box and press Enter. To find all declined leases, type <i class="monospace">state:declined</i> in the
            search box. The engine will find all matching leases on the monitored Kea servers running

                >lease_cmds hooks library</a
            >. The Kea servers not running this hooks library are excluded from the search.

                The search engine will look for the specified lease on all monitored Kea servers having the lease_cmds
                hooks library loaded. It may return multiple leases for the same IP address or delegated prefix when Kea
                servers are configured to share the lease information via High Availability hooks library or shared
                lease database.
